 ## Cross Platform Support
 
-ONNX runtime ecosystem now supports Phi3 mini models across platforms and hardware. You can find the optimized ONNX models [here](https://aka.ms/Phi3-ONNX-HF).
+ONNX runtime ecosystem now supports Phi-3 Mini models across platforms and hardware. You can find the optimized ONNX models [here](https://aka.ms/Phi3-ONNX-HF).
 
 Optimized Phi-3 models are also published here in ONNX format, to run with ONNX Runtime on CPU and GPU across devices, including server platforms, Windows, Linux and Mac desktops, and mobile CPUs, with the precision best suited to each of these targets. DirectML support lets developers bring hardware acceleration to Windows devices at scale across AMD, Intel, and NVIDIA GPUs.  
 Along with DirectML, ONNX Runtime provides cross platform support for Phi-3 across a range of devices CPU, GPU, and mobile.
